ALFRED H. HUMPHREY AND HUBERT R. HUMPHREY, OF NEW YORK, N. Y.

GAS-LAMP.

Specification of Letters Patent.

Patented June 11, 1907.

To all whom, it may concern.-

Be it known that we, ALFRED H. HUM- PHREY and HUBERT R. HUMPHREY, citizens of the United States, residing at New York, county of New York and State of New York, have invented certain new and useful Improvements in Gas-Lamps, of which the folowing is a specification.

This invention relates to improvements in gas lamps.

The objects of this invention are, first, to rovide an improved mantle support for gas amps having a group of inverted burners by which the mantles are so supported as to be quickly and easily placed in position and are completely and conveniently accessible. Second, to provide an improved mantle support for inverted burners by which the mantles'are so supported that the liabilit of injury in adjusting and arranging is ,re need to a mini.- mum. Third, to provide an im roved mantle su port for inverted burners y which the manties are so held that they are not likely to be injured by the jarring of the lamp.

Further object, and objects relating to structural details, will definitely appear from the detailed description to follow.

\Ve accomplish the objects of our. invention by the devices and means described in the following specification.

The invention is clearly ed out in the claims.

A structure embodying the features of our invention is clearly illustrated in the accomplanying drawing forming a part of this speci cation, in which, j

Figure 1 is a vertical section of a gas lamp embodying the features of our invention, taken on a line corresponding to line l--1 of Fig. 2, portions being shown in full lines, and the globe being shown open and the mantle support lowered, by dotted lines. Fig. 2 is a horizontal section taken on a line correspond ing to line 2-2 of Fig. 1, the mantle support being swung to one side. Fig. 3 is an enlarged perspective of the locking sleeve C.

In the drawing, the sectional views are taken looking in the direction of the little arrows at the ends of the section lines, and similar letters of reference refer to similar parts throughout the several views.

Referring to the drawing, in the structure illustrated the burners D are grouped about a defined and pointchimney A, which is supported from the gas.

supply pipe F. The as supply pipe F delivers to a ring E by which the burners are supported and through which the chimney A is arranged. On the lower end of the chimney A is an outwardly projecting flange A having a downwardly turned rim A thereon. The inverted burners D are arranged through this flange A as clearly appears in Fig. 1 of the drawing.

The plate-like mantle holder B is preferably arranged to fit quite closely within the downwardly projecting rim of the chimney "flange. .The mantle holder B is provided with openings adapted to receive the mantles G, the same being dropped through from the upper side. The mantles are preferably suspended from rings g, which fit into the openings in the holder and are provided with projecting ears or lugs g which rest upon the same; see Fig. 2.

The holder B is carried by a rod B which is adjustably arranged through the flange of the chimney and also through the flange h of the band H. The band H incloses the lower portion of the burners and forms the lower part of the lamp casing, the upper portion not being here illustrated. The rod B is provided with a stop S which engages under the flange A when the mantle support is in its adjusted position. On the upper end of the rod B is a sleeve C having a longitudinal slot therein. The rod B is also provided with a laterally projecting pin or fin or piece I) at its upper end which is engage by the sleeve for holding the mantle su port in position. The upper end of the sl eeve is cam shaped or spiral so that by turning it under the pin 1) the supporting rod B is drawn up until its stop, S engages. The sleeve 0 is preferably provided with a finger piece C for convenience in manipulating. To lower the mantle support to the position indicated by dotted lines in Fig. 1, the sleeve C is turned until the slot therein is under the pin 5 which permits the same to drop. It can then be swung out to one side as indicated in Fig. 2. It is evident that when in this position, the mantles can be easily inspected and renewed as desired By this arrangement, the mantles are supported so that they are entirely accessible and are all adjusted in proper relation to the burner tips at the same time. This adjusting may be done Without liability of injury to the mantles. If it should be necessary to renew only one of themantles, it can be done without danger to the other mantles.

The plate or holder B is preferablyformed of some material which is a non-conductor of heat, so that the heat is not carried away from the mantles, and so that it is not conveyed to the other parts of the lamp. It also serves the purpose of a reflector, giving valuable results in this respect and adding to the attractive appearance of the lamp. We preferably use magnesia and like materials for this'purpose. in addition to the advantages mentioned, if carbon from the burners should be deposited thereon, it soon burns ofl and is not collected thereby, as is the case Where the case is formed of brass or like metals.

As before stated, the support is held veryfirmly to the lamp so that the mantles are not likely to be injured by jarring or vibrations.

The globe [is preferably supported by securing the same to a ring I, which is pivoted at one side, as at J, so that it may be swung down as is indicated by dotted lines in Fig. 1. The globe is preferably held'in its closed po sition by the thumb-screw K.

It is evident that our improved mantle support is very simple in its operation and tgilat the mantle may be arranged very rap- 1 v.

We have illustrated and described our improved mantle support in detail in the form preferred by us on account of structural simplicity and economy and convenience in use, although we are aware that it is capable of considerable variation in structural details without departing from our invention.
